ELECTRICAL CHARACTERISTICS—3.3 V PRIMARY INPUT SUPPLY/3.3 V SECONDARY ISOLATED SUPPLY
3.0 V ≤ VDD1 ≤ 3.6 V, VSEL = GNDISO; all voltages are relative to their respective ground. All minimum/maximum specifications apply over
the entire recommended operating range, unless otherwise noted. All typical specifications are at TA = 25°C, VDD1 = 3.3 V, VISO = 3.3 V,
VSEL = GNDISO.
